Title: Paper sheet detector
Inventor: YOSHIDA SEIJI
IPC: G06K13/067
Filed: 1992-11-16
Abstract: PURPOSE:To carry out an exact judgment by judging the existence of a paper sheet based on a value detected by an optical sensor element. CONSTITUTION:When a power switch is turned off with a printing paper of high quality kept on a paper conveyance route, for example, a control program stored in the program memory range 28 of a ROM 28 starts. A reflection type photo sensor 20 converts a current value according to the reflected light into voltage to be detected, and the detected value is inputted in a CPU 24. The CPU 24 synchronizes with a fixed cycle or paper feed to read out the output value (referred to as the output of a photo sensor 20). The CPU compares the input value with the first reference value 28 which is stored in the first reference value of a ROM. Since a printing paper of superior quality has high light reflectance, the input value becomes larger than the first reference line for taking a paper existence process. It is, thus possible to judge the existence of paper exactly.

Title: Semiconductor integrated circuit
Inventor: NAKAGAWA KAORU
IPC: H01L27/08
Filed: 1986-12-22
Abstract: PURPOSE:To lower an oscillation frequency and to save power consumption, by providing a constant current generating means between a power source potential supplier and a self-exciting oscillation circuit in which the output of an inverter at the final stage of plural cascade-connected inverters is feedback-connected to the input of the inverter at the first stage. CONSTITUTION:The plural inverters I1-I5 are cascade-connected, and the self-exciting oscillation circuit is constituted by connecting the output of the inverter I5 to the input of the inverter I1, and an N-channel MOSFET Q1 is connected between the common contact Nl of the load use N-channel MOSFETs Q11-Q51 of the inverters I1-I5 and a power source VCC. The gate of the FETQ1 is connected to a resistor R1 between the power source VCC and an earth power source VSS, and the connection point of a Zener diode D1. When the potential of the power source VCC rises, the conduction resistance of the FETQ1 is increased by that share, and a current being permitted to flow from the power source VCC to the common contact N1 becomes constant invariably, then, the potential of the contact N1 is lowered. In such way, the oscillation frequency is set at a low level, and also, a stable oscillation frequency can be obtained even when a voltage fluctuates, and the power consumption of an integrated circuit in a standby state can be reduced.

Title: Method of controlling reactive power compensator
Inventor: TAKEI HIDEMI
IPC: H02J3/18
Filed: 1988-12-02
Abstract: PURPOSE:To improve reliability and economic efficiency by constituting a control system of only two control circuits to duplicate it and surely detecting and informing abnormality in the control system. CONSTITUTION:The control system is provided only with two control circuit, i.e., a normal control circuit 10a and a stand-by control circuit 10b, to duplicate it and the gain of the circuit 10b in an opened loop state is reduced almost up to the gain of a closed loop. Thereby, the voltages of amplified voltage signals outputted from both the control circuits 10a, 10b and the phases of gate pulses are not influenced by a control shear or the dispersion of parts. Only when abnormality such as a failure in a circuit is generated in either circuit, discrepancy in the voltages of the amplified voltage signals of both the circuits 10a, 10b or the phases of gate pulses is detected and abnormality in control can be surely detected and informed. Thus, reliability and economic efficiency can be improved.

Title: Formation of thin silicon oxide film by plasma cvd method
Inventor: WATABE YOSHI
IPC: H01L21/316
Filed: 1989-11-24
Abstract: PURPOSE:To reduce the leakage current of a thin silicon oxide film to be formed and to improve electric properties by limiting the flow rate of a gaseous raw material containing silicon atoms at the point of time when electric discharge is initiated and then increasing the flow rate. CONSTITUTION:In a plasma CVD method, the flow rate of N2O is made constant and the flow rate of SiH4 is changed according to the state of electric discharge. An rf electric power is supplied to an rf electrode at a time t1. Electric discharge is initiated in the space in front of a substrate, and plasma is produced. The supply of the rf electric power is stopped at a time t2, and electric discharge is stopped. During the duration T1 of the above electric discharge, the flow rate of N2O is set at a fixed value. The flow rate of SiH4 is set at zero at the point of time when electric discharge is initiated, and, during the prescribed period T2 where the state of electric discharge is transient, the flow rate of SiH4 is increased, e.g. by change characteristics in terms of quadratic function. Further, the flow rate of SiH4 is set at about 30sccm at a time t3 and held at the above fixed value during the stationary state until electric discharge is stopped. Owing to the above gas flow rate control, film forming velocity can be improved.
